Abstract

Growth inhibition can be interpreted as a compound that affects the plant physiology process. Its influence can stimulate and inhibit the physiology of plants. One of the growth inhibitions that can be used to inhibit growth is ethrel with ethephon active ingredient. The application of ethepon results in the growth of plant obstacles. The purpose of this research was to study the effect of ethrel concentration which influenced on vegetative growth and production of two varieties of cassava plant. This research used the UJ 3 and Kasetsart varieties of cassava cuttings with 25 cm length and age of 8-12 months. The treatments were arranged factorially (8 x 2) in a randomized block design with 4 replications used as a block, each block consisted of 16 sub samples. The first factors were the treatment of eight different ethrel concentrations as 0; 0,5; 1; 1,5; 2; 2,5; 3; and 3,5 ml/l. The second factors were two types of cassava varieties haved UJ 3 and Kasetsart. Ethrel was applied through leaves when the plants were 60 days after planting with the volume of 50 ml per plant. Variables observed in this research were plant height; number of fresh leaves; wet weight of leaves, stems, and roots; and dry weight of leaves, stems, and roots. The result showed that ethrel treatment inhibited elongation of stem and decreased wet and dry weight of leaves, stem and roots of cassava plants in UJ 3 variety. Key words: cassava, ethrel, varieties.
